    摘要: A bitline sense amplifier includes a pre-sensing unit and an amplification unit. The pre-sensing unit is connected to a first bitline and a second bitline, and is configured to perform a pre-sensing operation by controlling a voltage level of the second bitline based on at least one pre-sensing voltage and variation of a voltage level of the first bitline. The amplification unit is configured to perform a main amplification operation by amplifying a pre-sensed voltage difference based on a first voltage signal and a second voltage signal. The pre-sensed voltage difference indicates a difference between the voltage level of the first bitline and the voltage level of the second bitline after the pre-sensing operation.

    摘要: An output circuit of a semiconductor memory device includes a first data path, a second data path and a third data path. The first data path transfers a sense output signal, and latches the sense output signal to output the sense output signal to a first node. The second data path transfers the sense output signal, and latches the sense output signal to output the sense output signal to the first node. The third data path latches a signal of the first node, and transfers the signal of the first node to generate output data. Accordingly, the semiconductor memory device including the output circuit can operate at a relatively higher frequency using a pseudo-pipeline structured circuit, which combines a wave pipeline structure with a full pipeline structure.
